434 EXPERIMENT STATION EECORD. 



August 1 yielded 1,464 and 1,580 lbs. per acre, respectively. In 1907 the cotton 

 topped August 3 yielded 1,808 lbs., as compared with 1,575 lbs. on the check plat, 

 and that topped August 26 yielded 1,780 lbs. as compared with 1,821 on the 

 corresponding untopped or check plat. 



Rows 3 ft. apart produced more cotton than those farther apart, in 1911, but 

 were not included in the 1909 test when 4-ft. rows gave greater yields than 

 either 5 or 6 ft. rows. In these tests the plants averaged 15 in. apart in the 

 row. In rows 3 ft. 8 in. apart, plants spaced 12 in. apart gave greater 2-year 

 average yields per acre than those spaced 20 or 30 in. apart. 



Poisoning the army worm on August 20 and 30 resulted in a yield of 1,414 

 lbs. of seed cotton per acre as compared with 767 lbs. on the untreated plats. 

 Paris green appeared to be more effective than arsenate of lead. 



II. Results from the McNeil Experiment Station, E. R. Ferris (pp. 14-21). — 

 Meteorological data are followed by a statement of the results of a variety test 

 in which Ashcraft Double Jointed Snow Bank, Trice, and Truitt 90-day pro- 

 duced the highest yields. 



A table states the 6-year average results secured in a test of various ferti- 

 lizers. The highest yields were obtained after applications of (1) 100 lbs. each 

 of cotton-seed meal and acid phosphate, and (2) 100 lbs, each of cotton-seed 

 meal, acid phosphate, and kainit. Both plats were on land on which cattle were 

 fed during the winter of 1902-3. On land on which cattle had not been fed the 

 highest yield followed an application of 200 lbs of cotton-seed meal and 100 lbs. 

 of acid phosphate. Ctotton planted April 1 gave 27S lbs. per acre as compared 

 with 289 lbs. from that planted April 15, 55 lbs. from that planted May 1, and 

 a total failure in ca.se of that planted May 15. 



III. Results from the Holly Springs Branch Experiment Station, C. T. Ames 

 (pp. 22-27). — In a variety test at this station the highest yields of lint cotton 

 per acre were given by Truitt 90-day, Broadwell Double Jointed, and Rowden 

 116. In the fertilizer test the highest yields followed applications of (1) 200 

 lbs. acid phosphate (2) 100 lbs. each acid phosphate and cotton-seed meal, and 

 (3) 200 lbs. cotton-seed meal, in the order named. Ten applications were 

 tested in this series of experiments and in a parallel series 7 of them were du- 

 plicated except that the applications were doubled in amount. In this series 

 much the highest yield followed tbe application of 200 lbs. each of cotton-seed, 

 meal and acid phosphate. These figures are for 1911. Another table states the 

 6-year average results in which the same applications were followed by the 

 highest yields but with less distinct advantage. In another fertilizer test in 

 1911 tbe highest yields followed applications of (1) 200 lbs. of cotton-seed meal 

 and (2) 400 lbs. of raw-rock phosphate. In a tOvSt of nitrogen sources supple- 

 mented in each case by 200 lbs. of acid phosphate the use of (1) 200 lbs. of 

 cotton-seed meal and (2) 80 lbs. of nitrate of soda gave yields somewhat 

 higher than those secured from the use of 150 lbs. of nitroline or 486 lbs. of 

 am,moline. The soil used has been in cultivation more than 50 years and is 

 characteristic of the poorer soils of the section. 



IV. Results from Delta Branch Experitnent Station, G. B. Walker (pp. 27- 

 29). — The Express and Triumph varieties excelled the others tested in value of 

 lint cotton per acre. 



In a spacing test in which the stalks stood from 18 to 24 in. apart in the row, 

 better yields were obtained from rows 3| ft, apart than from rows 3, 4, 5, or 6 

 ft. apart.

 of cotton planting, fertilizer, and cultural investigations in India.
